Jojora

From the Super Mario Wiki

Jojora is mysterious fairy-like girl who lives in Joke's End. She's just there because her friend's cousin's ancestor was the person who owned the place. Mario and Luigi have to fight her and one of her friends during a tea party in Mario & Luigi: Superstar Saga.

After making it through the entire palace, the brothers find Jojora in her room, where she asks them to sit down, and tells them that she admires their perseverance. She then asks which "friend" they would like to meet for tea. After the Bros. select one, the chosen "friend" falls down from the ceiling and fights alongside Jojora against the brothers. When Mario and Luigi battle her they find she has a high defense. In fact, most attacks only do one HP's worth of damage.

She also can wave her wand at them causing them to freeze, but if a Hammer strike is executed when she walks up to a Bro., the brothers can counter the attack and knock it out of her hands causing her to run away crying, "Eek! Uncool, you creep!" But this is short-lasting, as she will soon find her wand and return to battle. Also, whenever the Bros. damage her friend while she is still on screen, she exclaims "You NEVER touch a lady without her permission!" and begins a snowstorm that can freeze both of the Bros., and recharge the two ladies. But if she herself is attacked, no side effects occur. Because of this, the Bros. will have to time their attacks so her friend is only damaged while Jojora is off getting her wand, and unable to begin a snowstorm.
